Trinity House is the home of the Incorporation of Shipowners and Shipmasters, an organisation dating back to the 14th century. Successive generations of masters and members of Trinity House have been closely involved in the history and maritime development of Leith. Thomas Brown designed the present Trinity House in 1816 on the site of the medieval mariner's hospital. Trinity House highlights include the magnificent Convening Room running the entire length and breadth of the upper floor and a Pandora's Box of
maritime memorabilia; Raeburn's painting of Admiral Duncan - a naval masterpiece and The Master's Room - a cosy room, still retaining its Georgian fixtures and furnishings.
